Subject: [PATCH v3 0/3] ALSA: hda/tas2781: Add tas2781 driver for SPI.

This patch was used to add TAS2781 devices on SPI support in sound/pci/hda.
It use ACPI node descript about parameters of TAS2781 on SPI, it like:
    Scope (_SB.PC00.SPI0)
    {
        Device (GSPK)
        {
            Name (_HID, "TXNW2781")  // _HID: Hardware ID
            Method (_CRS, 0, NotSerialized)
            {
                Name (RBUF, ResourceTemplate ()
                {
                    SpiSerialBusV2 (...)
                    SpiSerialBusV2 (...)
                }
            }
        }
    }

And in platform/x86/serial-multi-instantiate.c, those spi devices will be
added into system as a single SPI device, so TAS2781 SPI driver will
probe twice for every single SPI device. And driver will also parser
mono DSP firmware binary and RCA binary for itself.
